I need engine help
I have a 350 in my 66 chevy truck it seemed to be laying down when accelerated or put into gear. this is what we have done, vacuum checked perfect all electrical checked paerfect distri and other ohms that you can check. I even put a new hei accel dizzy on we timed it with a light but its just keeps laying down Im thinking timing chain gears they are new but that the only thing I can thing of now any thoughts any one before I rip it a part to look at the gears??????

Checked the fuel filter and cleaned the carb?

Re: I need engine help
Is it stock or just start all of a sudden? I think of my truck when i put dual carbs and huge cam in it and i had to put a stall converter in it so it would move, that comes to mind to me

Re: I need engine help
Sounds like accelerator pump going bad in the carb to me. Bump the timing up 2-4 deg and see if it gets better.

Re: I need engine help
If the truck was an original 6 cyl, the fuel line is only 5/16", could be starving a bit for fuel volume.
Also a new carb doesn't mean it's a good one-it happens. Sounds to me more like a fuel problem, not a major mechanical thing.Is the vac advance on a ported or timed vac port on the carb? |

Re: I need engine help

Re: I need engine help
For troubleshooting purposes, I would install a see thru fuel filter in line. You can then visibly see if the fuel volume goes down when you put it in gear. It will take two people to do this.

Re: I need engine help
timing at 14 without vac total was 43 we did check the timing gears and it dead on, so we put it all back together and I bought a clear gas filter and I took the lines off and pour the gas in a glass and we got sediment not much but we also got rust. I took the carb a part and cleaned everything and blew it out, I think that the fuel maybe my problem. I hope

Re: I need engine help
I would agree with accelerator pump...the minute you move the throttle it should be spraying fuel from the pump shooter..... it may have a plugged channel or the rubber on the pump itself is hard and not sealing in the well.....
